The present poster develops a pin on disc machine that works under standard ASTM G99, which parameters design were established according to the necessities and the characteristics of the design when its compared with the competence. Also, an added implement allows it to increase the pressure contact of area, resulting in bigger stresses, being the case for the spherical tungsten...
Evaluar la viabilidad económica de construir un reactor nuclear AP1000 en Baja California Sur (México), comparándolo con plantas de ciclo combinado (CCGT), para impulsar la transición energética limpia y abordar desafíos humanitarios como la salud pública. Obteniendo que el AP1000 tiene un costo nivelado de energía (LCOE) de $129.44/MWh (dólares estadounidenses) con un beneficio total de 148 mil millones de...
This study investigates the effect of thermochemical treatments—boriding, nitriding, and sequential boronitriding—on AISI 420 ESR stainless steel. Samples were treated and analyzed via microscopy, microhardness testing, adhesion evaluation, and energy-dispersive spectroscopy (EDS). Boriding produced the highest surface hardness (~1250 HV₀.₀₅), representing an increase of approximately 733% over the base material, but showed poor adhesion. Nitriding showed lower hardness (~1050 HV₀.₀₅),...
